TSW4806EVM

The TSW4806 evaluation module (EVM), one of the new Texas Instruments (TI) low-cost evaluation tools,

uses an LMK04806 dual-PLL clock-jitter cleaner and generator, providing a low cost, low-noise, portable

clocking solution for use with TI's high-speed data converter EVMs. Together with the accompanying

Labview-based Graphical User Interface (GUI), it is a complete clocking tool used with the other low-cost

TI evaluation tools providing a complete system that captures and evaluates data samples from ADC

EVM’s and generates test patterns to DAC EVM’s. The EVM's on-board EEPROM comes with several

pre-programmed register settings so the board can begin running without using the GUI interface. The

EEPROM provides the memory necessary for saving up to eight custom LMK04806 configuration settings.

These settings are quickly loaded using on-board switches.

TSW4806EVM

An option for installing a commercial-quality voltage-controlled crystal oscillator (VCXO) is available on the

board, providing a known reference point for evaluation of the device performance in dual-PLL mode.

The board features an on-board 10-MHz reference oscillator for internal clock reference and output

reference source.

The on-board EEPROM programs the LMK04806, providing several factory pre-programmed settings. The

board provides 491.52-, 245.76-, 122.88-, and 61.44-MHz outputs after power up (or after pushing the

RESET button) if the four dip switches are in their default 0000 position (all up). A software GUI is also

provided allowing custom configuration of the LMK04806.

The EVM supports any of the four devices offered in the LMK04800 family with the default device being

the LMK04806.

TSW4806EVM

Quick-Start Setup Procedure

1.1.1 Hardware Setup

1. Connect one end of the provided 5-VDC power cable to the barrel connector (J8) of the TSW4806.

Connect the other end to a +5 VDC power supply capable of providing 3 amps. If using the banana

jacks, connect the positive end to J10 and the negative end to J9.

2. Make sure the four dip switches (SW1) are in the factory default position (all up). This corresponds to

an address of 0000 and is also indicated by four LED’s, all of which indicate OFF. The address for the

on-board EEPROM is selected by the CPLD, dependant upon the switch settings.

3. Turn on the +5 VDC power supply. After power-up, the 5-VDC LED illuminates. The on-board CPLD

automatically loads the LMK04806 from the configuration file stored in the EEPROM at the location

determined by DIPSWITCH, SW1. After the LMK is configured, the green LOCK LED turns on. This

indicates that the PLL of the LMK04806 is locked to the 10-MHz on-board reference source. The

output SMA’s now provide the following frequencies:

J7 – 61.44-MHz CMOS output. AC coupled, from CLKOUT10P of LMK04806.

J15 – 61.44-MHz CMOS output. AC coupled, from CLKOUT10N of LMK04806.

J17 – 61.44-MHz CMOS output from CLKOUT11P of LMK04806.

J4 – 122.88-MHz CMOS output from CLKOUT0P of LMK04806.

J1 – 245.76-MHz CMOS output from CLKOUT5P of LMK04806.

J2 – 491.52-MHz CMOS output. AC coupled, from CLKOUT3P of LMK04806.

J3 – 491.52-MHz CMOS output. AC coupled, from CLKOUT3N of LMK04806.

J6 – 491.52-MHz CMOS output from CLKOUT2P of LMK04806.

Note: If the LOCK LED does not turn on after power up, ensure the four dip switches are set to 0000

(all in the up position) and push the reset button (SW2).

TSW4806 GUI Operation

SLAU454A–July 2012–Revised April 2016

TSW4806EVM

3 TSW4806 GUI Operation

1. Apply 5 V to the board. Start the TSW4806 GUI by going to the Start Menu →All Programs →Texas

Instruments ADCs →TSW4806 GUI.

2. Make sure the USB Status green indicator lights.

3. Click the Load button and select the file named 122.88_61.44.txt. Click OK.

4. Click Send All. At this point, the LED labeled D1 on the TSW4806 lights, indicating a PLL lock.

5. Configure the board such that a 122.88-MHz clock is present on SMA’s J2, J3, J4, and J6. SMA’s J1,

J7, J15 and J17 have 61.44-MHz clock outputs.

The output clocks are determined by the value the internal VCO is running at and the divide value

selected for the output. In this example, the VCO is operating in single PLL mode and locked to the on-

board 10-MHz oscillator. The value the PLL2 is setting the VCO too is determined as follows:

REF CLK / R divider = VCO / N divider / Prescaler

10MHz / 125 = VCO / 3840 / 8

VCO = 2457.6MHz

Figure 5. PLL2 Settings

Using the divided values shown in Figure 6 results in the following for Clock Out 0, 1, 2, and 3: 2457.6 / 20

= 122.88 MHz.

Using the divided values shown in Figure 6 results in the following for Clock Out 6, 7, 8, 9, 10 and 11:

2457.6 / 40 = 61.44 MHz.

5 Optional Features and Configurations

5.1 Clocking

The EVM board comes with the LMK04806 device which has an internal VCO frequency range of

2370–2600 MHz. If the desired clock is not derived from this frequency range using integer dividers, then

swap this device out for another LMK04800 with a different VCO range. Determine which LMK04800

works for the desired frequency range by consulting the LMK04800 data sheet (SNAS489).

Set up the LMK04800 in clock distribution mode or as a clock generator using single or dual PLL mode.

The different modes of operation are listed below.

1. External Clock Mode: Setting up the LMK4806 in clock distribution mode permits the use of an

external clock source. This allows for coherent sampling by providing a clock that is synchronized to

the other signal sources. The TSW4806 GUI includes a configuration file for the external clock mode.

This file is located in the GUI installation directory in the folder Configuration Files and is named

external_clock.txt. Load the file by clicking the Load button, navigating to the correct folder, selecting

the file, and clicking OK. Provide an external clock through the CLKIN1 SMA J12 connector on the

TSW4806 board.

2. On-board Clock using Single PLL Mode: This is the default mode of operation for the TSW4806.

The 10-MHz on-board oscillator acts as the reference for the PLL and the divided down internal VCO

acts as the clock source. All of the factory provided configurations stored in the EEPROM and the

provided files in the Configuration Files folder not mentioned elsewhere in this document operate in

this mode. Use an external reference (2 Vp-p min) in place of the on-board oscillator. Operate in this

mode by providing a clock source to SMA J11, and moving the shunt on jumper JP5 to pins 2-3. The

10-MHz oscillator is now disabled by moving the shunt on jumper JP4 to pins 2-3.

3. On-board Clock using Dual PLL Mode: In this mode of operation, providing a low-frequency

reference generates a synchronized sampling clock at a higher frequency. The reference comes from

any source, such as a 10-MHz reference from a piece of test equipment, this allows synchronization

between all signal sources and is used for coherent sampling. Installing a VCXO at Y2 allows the use

of this mode. Update the loop filters if there is a change in reference or VCXO. Use the Clock Design

Tool (http://www.ti.com/tool/clockdesigntool) for designing the loop filters and PLL settings based on

the reference, VCXO, and output frequencies.
